Very fast service, best quality of the service manual and the schematics
 ;
This service manual of the old video cassette recorder VT-LC50EM is very good readable even the tiniest numbers (i.e. IC-pins). The circuits are very clear. Many details of the schematic are very good described but in GERMAN language. Many schematic details - but complete at all. Common background information of several details are enclosed and physical knowledge of the TFT liquid crystal display for example. The manual lacks PCB drawings. If you understand german I would recommend this manual for you.

Hi, this is a very clear manual, nice copy, not quite up to the standard of the very best available but better than many others. I think the price was especially fair for a hard to find manual and I would certainly use this manual seller again. Recommended.

This schema available for me in good condition. I would highly recommend.

Thanks for this "hard to find" service manual.
I apreciate the good quality of scanning and the pages scanned in A3 format.

Number and cursor buttons are used for service adjustments. The OK button stores the settings. The yellow button hides/shows the service menu to simplify the picture adjustments. Making adjustments for different picture formats Make all adjustments with PAL signal unless otherwise mentioned. Make 4:3 set adjustments with normal 4:3(CLASSIC) picture format and 16:9 set adjustments with wide picture format. Then make the necessary adjustments with other picture formats/signals. The required adjustments are shown in the table below. Note! Check the configuration of the TVset before making the adjustments and make only the necessary adjustments. 3. Store the new value by pressing the OK button. Making a service adjustment 1. Give a two digit code which determines an adjustment (e.g. 00 = vertical shift, see the following tables) with the number buttons. You can also select the adjustment with cursor buttons (up-/down). Note! Power supply and UG2 adjustments before picture geometry adjustments. must be done Note! To avoid incomplete adjustments store each adjustment in the memory immediately after an adjustment has been made. If an adjustment has to be made separately for different picture format/signal, select first the normal mode by pressing the TV button and select then the desired picture format/signal.
